In 2005, I talked with Greg Critser about “Generation Rx,” his book on how Big Pharma has gotten Americans on more medications than ever before.

Today, Critser was back to talk about his new book, “Eternity Soup,” about the anti-aging industry, where people spend billions of dollars each year trying to defy (and deny) time. We talked about his own hormone therapy after suffering a concussion and others who have used bizarre treatments for more ego-driven reasons. Critser also describes a wild convention of anti-aging products he attended.
